My opinion is that historical religions were probably no more or no less based on a drug culture than is so-called western civilization.
It is hard to believe that the hundreds of myths of the past were drug induced:
For example, was the Epic of Gilgamesh a consequence of mind twisting drugs? or Homer's Odyssey, or the Greek myths, or the ancient Egyptian "Book of the Dead", or the story of Santa Clause, or Arthur and the knights of the round table, or the stories of the Gnostics, or the stories written by the Essenes, ...
It seems to me that the human mind has a strong inclination to produce mythology and that these myths are relatively primitive attempts to define, explain and understand human morality.
